-# ComfyUI-Mango-Random-node
-comfyui Random read node, can specify the directory, random or sequential read image, text and video content
+# 🥭 Mango Random Nodes 🥭
+
+Welcome to **Comfyui Mango Random Nodes**! 🚀 This is a random file node tool designed for ComfyUI, making your workflow more flexible and interesting. Whether for creative projects or daily use, our tools help you easily access random files and images.
+
+## Included Nodes 🌟
+
+- 🎲 **Random File Path**  
+  Randomly selects a file from a specified directory and returns the file path as a string.
+
+- 🖼️ **Random Image Path**  
+  Gets images and their corresponding text content (with the same filename) from a specified folder. Supports two modes:
+  - Sequential Cycle: Outputs files in order by filename
+  - Fully Random: Randomly selects and outputs images
+
+- 🎬 **Random Video Path**  
+  Gets videos and their corresponding text content (with the same filename) from a specified folder. Supports two modes:
+  - Sequential Cycle: Outputs files in order by filename
+  - Fully Random: Randomly selects and outputs videos
+
+## Installation 🛠️
+
+### Method 1: Clone Repository to `custom_nodes` Folder
+
+1. **Clone Repository:**
+   Open Command Prompt or PowerShell and run:
+   ```bash
+   git clone https://github.com/mango-rgb/ComfyUI-Mango-Random-node <path/to/comfyui/custom_nodes>
+   ```
+   Replace `path/to/comfyui` with your actual ComfyUI installation path.
+
+2. **Restart ComfyUI:**
+   Restart the ComfyUI server to load the new nodes.
+
+### Method 2: Install via ComfyUI Manager
+
+1. **Open ComfyUI Manager**
+
+2. **Search for** `Mango Random Nodes`
+
+3. **Install Nodes:**
+   Click the `Install` button to install the nodes.
+
+4. **Restart ComfyUI:**
+   Restart the ComfyUI server after installation.
